Silencing the already quiet P180

I wanted to post a some pics since I have torn apart my rig & reworked it too many times to count lol. I am way obsessed with noise and secondly, cable management. I am still not finished, but I am close. I want a silent pc, not a quiet pc. So with my latest toys I am almost at complete inaudibleness. The only thing I can barely hear now is my rev 1 NV5 even at the 5V level. It's a little whiny, but will be replaced in 2 days. The P180 even deadened my raptor beyond hearing.
I have opted for no fan on top: main reason is the noise. Noise emanates from this opening and imo totally takes away from the achievable silence of this case. Though some here have found good results with the cooling potential the top fan can offer as an intake, I just found it too noisy (even with a slow, silent 120mm). I use the XP120 and with a PWM controlled 120mm (Nexus) atop, you can't hear it anyway. Reason being is that the noise emmited from fans embeded w/in the case (CPU/HSF & bottem chamber fan) are drastically dampened. The crucial noise locations are the top, rear, intake, and psu fan if utilizing a rear exhaust 80mm. These are the locations you want to put your quietest (low rpm'rs) fans, or in the psu's case, get one w/ a bottem/top mounted 120mm or do a fan mod.
In the pics, my cover for the top of the P180 to block the top fan mount is not there. Thats because my P180 fits in a desk that measures the exact height of the case. So a shelf is my cover. The bottem Nexus is on a 2nd resistor (not manually controlled) that drops its rpm to around 700. The intake and the cpu Nexus's are controlled via SpeedFan. The exhaust is as well. I think cable management is so important to achieve good cooling. I am still at work with that. The psu is a pcp&c 425W and I have swapped the fan. All fans softmounted. The screenshot is what my pc idles @ 80% of the time (I consider using WMP idle, but it ramps up cpu temps 1-2C). My load temps (BF2 for 1 hour/Prime Torture is between 44-47C). I run RMClock and under loads my 3500+ is @ 2.4GHz and my 6800GT is @ 432/1170. With the right tools and some time, even a moderately oc'd high performance pc can achieve total silence.

i dont think there is very much you can do to make it more quiet then it already is unless u got to passive cooling on everything. one question. how far is it from your 24 power plug on ur mobo to the psu?

Too long too hide it w/o an extension. In inches? I'd guess about 12-14 inches by way of a straight line if there were one.

ok thanks. the only thing i might beable to sugest is rubber feet for vibration dampaning if you dont have them already.

lol i did just get the fans yesterday. I am a copycat what can I say ;) How are your temps and do you run the Nexus's on a controller or SpeedFan?

very nice!!
I like attention to detail!!
I also like a clean machine wiring and all!!

My fans are run through a Sunbeam Rheobus fan controller. But I usually run most of my fans at full speed anyway (1000rpm). I just got the XP-120 and this thing rocks (especially with the nexus). My case temps are great, but my CPU is a P4 Prescott 3.0, so my cpu temps are gonna be ALOT higher than yours!

CPU idle: 42
CPU load: 57 (actually really low for a prescott)

mobo idle: 28
mobo load:33

GPU idle: 38
GPU load: 53

replacing the stock antec (on low) in the lower cage with a nexus dropped my HDs to around 27-29c

But you just can't beat a near silent machine! Its so quiet I have to look at the front LEDs to see if its on or not :Q
